Professor Gordon Wetzstein and EE PhD candidate David Lindell, have created a system that reconstructs shapes obscured by 1-inch-thick foam. Their tests are detailed in, "Three-dimensional imaging through scattering media based on confocal diffuse tomography", published in Nature Communications.

Gordon Wetzstein reports, "A lot of imaging techniques make images look a little bit better, a little bit less noisy, but this is really something where we make the invisible visible. This is really pushing the frontier of what may be possible with any kind of sensing system. It's like superhuman vision."

"We were interested in being able to image through scattering media without these assumptions and to collect all the photons that have been scattered to reconstruct the image," said David Lindell, EE PhD candidate and lead author of the paper. "This makes our system especially useful for large-scale applications, where there would be very few ballistic photons."

In order to make their algorithm amenable to the complexities of scattering, the researchers had to closely co-design their hardware and software, although the hardware components they used are only slightly more advanced than what is currently found in autonomous cars. Depending on the brightness of the hidden objects, scanning in their tests took anywhere from one minute to one hour, but the algorithm reconstructed the obscured scene in real-time and could be run on a laptop.

"You couldn't see through the foam with your own eyes, and even just looking at the photon measurements from the detector, you really don't see anything," said David. "But, with just a handful of photons, the reconstruction algorithm can expose these objects – and you can see not only what they look like, but where they are in 3D space."

Professor Dan Boneh's Hidden Number Problem helped academic researchers identify and resolve a vulnerability. Dan leads the Applied Cryptography Group.

The attack – known as Raccoon – affects TLS 1.2 and previous versions, which specify that any leading bytes beginning with zero in the premaster secret are stripped out. The premaster secret is the shared key used by the client and server to compute the subsequent TLS keys for each session.

"Since the resulting premaster secret is used as an input into the key derivation function, which is based on hash functions with different timing profiles, precise timing measurements may enable an attacker to construct an oracle from a TLS server. This oracle tells the attacker whether a computed premaster secret starts with zero or not," the description of the attack says.

"Based on the server timing behavior, the attacker can find values leading to premaster secrets starting with zero. In the end, this helps the attacker to construct a set of equations and use a solver for the Hidden Number Problem (HNP) to compute the original premaster secret established between the client and the server."

In addition to leading the applied cryptography group, Dan co-directs the computer security lab. His research focuses on applications of cryptography to computer security. His work includes cryptosystems with novel properties, web security, security for mobile devices, and cryptanalysis.

Professor Shanhui Fan's rooftop cooling system could eventually help meet the need for nighttime lighting in urban areas, or provide lighting in developing countries.

Using commercially available technology, the research team has designed an off-grid, low-cost modular energy source that can efficiently produce power at night.

Although solar power brings many benefits, its use depends heavily on the distribution of sunlight, which can be limited in many locations and is completely unavailable at night. Systems that store energy produced during the day are typically expensive, thus driving up the cost of using solar power.

To find a less-expensive alternative, researchers led by professor Shanhui Fan looked to radiative cooling. Their approach uses the temperature difference resulting from heat absorbed from the surrounding air and the radiant cooling effect of cold space to generate electricity.

In The Optical Society (OSA) journal Optics Express, the researchers theoretically demonstrate an optimized radiative cooling approach that can generate 2.2 Watts per square meter with a rooftop device that doesn't require a battery or any external energy. This is about 120 times the amount of energy that has been experimentally demonstrated and enough to power modular sensors such as ones used in security or environmental applications.

"We are working to develop high-performance, sustainable lighting generation that can provide everyone–including those in developing and rural areas–access to reliable and sustainable low cost lighting energy sources," said Lingling Fan, EE PhD candidate and first author of the paper. "A modular energy source could also power off-grid sensors used in a variety of applications and be used to convert waste heat from automobiles into usable power."

Additional authors include Wei Li (EE PhD candidate), and post-doctoral researcher Weiliang Jin, PhD, and Meir Orenstein (Technion-Israel Institute of Technology).

Professor Gordon Wetzstein and team use AI to revolutionize real-time holography.

"The big challenge has been that we don't have algorithms that are good enough to model all the physical aspects of how light propagates in a complex optical system such as AR eyeglasses," reports Gordon. "The algorithms we have at the moment are limited in two ways. They're computationally inefficient, so it takes too long to constantly update the images. And in practice, the images don't look that good."


Gordon says the new approach makes big advances on both real-time image generation and image quality. In heads-up comparisons, he says, the algorithms developed by their "Holonet" neural network generated clearer and more accurate 3-D images, on the spot, than the traditional holographic software.

That has big practical applications for virtual and augmented reality, well beyond the obvious arenas of gaming and virtual meetings. Real-time holography has tremendous potential for education, training, and remote work. An aircraft mechanic, for example, could learn by exploring the inside of a jet engine thousands of miles away, or a cardiac surgeon could practice a particularly challenging procedure.

In addition to professor Gordon Wetzstein, the system was created by Yifan Peng, a postdoctoral fellow in computer science; Suyeon Choi, an EE PhD candidate; Nitish Padmanaban, EE PhD '20; and Jonghyun Kim, a senior research scientist at Nvidia Corp.

James Gibbons has always been ahead of the times.

 

In a Q&A conversation with Stanford Engineering, Professor Emeritus James Gibbons shares lessons in remote learning experiments from the 1970s.

At the time of the research, James was asked to join President Nixon's Science Advisory Council, which was studying the effectiveness of televised education – dubbed "Tutored Video Instruction, or TVI".

A subset of the Science Advisory Council started by reviewing a very large study comparing televised classes with live classes. The study covered every subject matter from math to arts, from kindergarten to a baccalaureate degree. It was a huge study, 363 different experiments.

The overall answer was: There is no significant difference in student learning between TV and live instruction.

As the technology evolved, James and his colleagues began working with Sun Microsystems to create what was called distributed tutored video instruction – DTVI. He reports:

 

"We imagined the students to be remote from each other. We provided each of them with a microphone and a video camera to support remote communication within the group. We did an experiment at two campuses of the California State University system where we had 700 students at the two universities. We ran a regular lecture, a TVI group and a DTVI group for every class. The DTVI students were in their own rooms, connected to each other through our early version of the internet."

"Sound familiar? Well, it should. This is exactly what Zoom does, right? In fact, it looked just like Zoom in the gallery view, with everyone wearing headsets and so forth. The results showed about the same performance academically, between TVI and DTVI, with each of them being superior to the live lecture class over a range of subjects."

 


In these days of COVID-19, everyone from parents to teachers to school administrators, not to mention the students themselves, is worried how this nationwide experiment in online learning is going to work out.

And from James' research findings, there should be no significant difference between online and in-person learning.

The current generation of neural implants record enormous amounts of neural activity, then transmit these brain signals through wires to a computer. But, so far, when researchers have tried to create wireless brain-computer interfaces to do this, it took so much power to transmit the data that the implants generated too much heat to be safe for the patient. A new study suggests how to solve his problem -- and thus cut the wires.

Research led by Professors Krishna Shenoy, Boris Murmann and Dr. Jaimie Henderson, have shown how it would be possible to create a wireless device, capable of gathering and transmitting accurate neural signals, but using a tenth of the power required by current wire-enabled systems. These wireless devices would look more natural than the wired models and give patients freer range of motion.

Graduate student Nir Even-Chen and postdoctoral fellow Dante Muratore, PhD, describe the team's approach in a Nature Biomedical Engineering paper.

The next step will be to build an implant based on this new approach and proceed through a series of tests toward the ultimate goal.

To advance quantum research during this exciting time, and help bridge Stanford's physics and engineering departments, the university is launching a new postdoctoral fellows program named after Felix Bloch, who was a theoretical physicist at Stanford and the university's first Nobel Prize winner.

The Bloch fellowship is awarded by the Q-FARM (Quantum Fundamentals, ARchitecture and Machines) initiative, which launched last year. Q-FARM emerged from Stanford's long-range planning process as part of a team focused on understanding the natural world. The initiative seeks to utilize the resources of both Stanford and the SLAC National Accelerator Laboratory to accelerate quantum research.

The first cohort of Bloch fellows was appointed this year and includes postdocs studying topics ranging from the fundamentals of quantum theory to computing and sensing applications.

Up to six fellows will be selected each year for a 2-3 year appointment, based on strong research proposals and previous accomplishments in the field. They are then jointly advised by at least two faculty members, which in most cases hail from different departments and schools, to foster interdisciplinary collaborations. The first cohort of Bloch fellows was appointed this year and includes postdocs studying topics ranging from the fundamentals of quantum theory to computing and sensing applications.

"These first five fellows had innovative proposals that connect research groups and establish collaborations that didn't exist previously," reports Prof. Jelena Vuckovic. "We also picked candidates who span all areas of Q-FARM: from theory to experiment, from algorithms to devices and circuits, from science to engineering."

The Q-FARM directors hope this diversity of interests and collaboration between departments will seed more creative projects and build lasting connections. The result will be a new generation of quantum scientists and engineers for academia and industry that honors the fellowship's namesake.
